Oil Pan Blocker for Automotive Industry

Oil Pan Blocker for Automotive Industry

Interested in developing an under-the-hood component that can take on high heat, while providing resistance to oil and other automotive fluids, an Automotive customer in Michigan partnered with Woodland Plastics to utilize our thermoset molding services for this oil pan blocker shown below.

Using BMC 675 – a thermoset polyester material – the oil pan blocker is injection molded in a single cavity from a 250-ton thermoset injection molding machine. The final part weights roughly 200 grams and measures 124mm in length x 98mm in width.
